Working conditions and strict restriction in production of radioactive wastes, especially of liquid wastes, in the nuclear power plant A-1 in Jaslovske Bohunice (Slovak Republic) during its decommissioning were the main reason of the development and testing of alternative decontamination processes to classical methods like bath chemical decontamination or bath electrochemical decontamination that are available in the NPP A-1. Decontamination processes based on the use of special foams, pastes, gels and coatings were developed for small application of local character. Expected extent of decontamination work related to elimination of consequences of a severe radiation accident in the reactor hall, character of the contamination and variety of contaminated surfaces were the initiation to the continuation of the development of the decontamination methods and appropriate application means in order to make their large-scale operational use possible. Results from tests and practical applications indicate possibilities of applicability of these decontamination methods even in decontamination of the reactor hall including all objects and equipment with the relative low production of secondary radioactive waste that can be processed by common methods in the NPP A-1.
